Hadoop Data Warehouse and Design Considerations

A data warehouse, also known as an enterprise data warehouse (EDW), is a large collective store of data that is used to make such data-driven decisions, thereby becoming one of the centrepiece of an organization’s data infrastructure. Hadoop Data Warehouse was challenge in initial days when Hadoop was evolving but now with lots of improvement, it is very easy to develop Hadoop data warehouse Architecture. This article will server as a guide to Hadoop data warehouse system design. Hadoop data warehouse integration is now a days become very much popular…

Migrating Netezza to Impala SQL Best Practices

Now a days everybody wants to migrate to Hadoop environment for their analytics that includes real-time or near real-time. In this post i will explain some best practices in Migrating Netezza to Impala SQL. Impala uses the standard SQL but still you might need to modify the source SQL when bringing specific application to Hadoop Impala due to variations in data types, built-in function and obviously Hadoop specific syntax. Even if the SQL is working correctly in Impala, you might consider rewriting it to improve performance. Read: Netezza Hadoop Connector…

Netezza Hadoop Connector and its Usage

Netezza Hadoop connector for Sqoop is an implementation of the Sqoop connector interfaces for accessing a Netezza data warehouse appliance from Hadoop cluster. Yom can export and import he data to a Hadoop cluster from various Netezza data warehouse environment. Netezza Hadoop connector is designed to use Netezza high-throughput data-transfer mechanisms to import and export data to Hadoop HDFS. This Connector for Netezza is a standard Sqoop extension that allows Sqoop to inter operate with Netezza Data warehouse appliance through Netezza JDBC drivers. This connector is already Cloudera Hadoop distribution…

Sqoop Architecture – Mappers with No Reducers

Sqoop is a tool designed to transfer data between Hadoop and various relational databases. You can use Sqoop to import data from a relational database management system (RDBMS) such as Netezza, MySQL, Oracle or SQL Server into the Hadoop Distributed File System (HDFS), transform the data and perform complex calculations in Hadoop MapReduce, and then export the data back into an RDBMS. Sqoop is based on a connector architecture which supports plugins to provide connectivity to external systems (RDBMS) .
